Harlow was also a noted expert on Pueblo pottery of the Southwest, publishing in this field as well as in physics. In fact, Harlow traded one of his favorite Pueblo pottery jars for this 1940 Harley Davidson and was known to ride it to nearby Pueblos in search of pottery. He donated his extensive collection of Pueblo pottery to the Museum of Indian Arts and Culture several years before his death. In 2016, Harlow’s autobiography was published in the collection Adventures in Physics and Pueblo Pottery: Memoirs of a Los Alamos Scientist.
